IMPROVEM ENT IN CULTIVATO RS.

Speeiiiention forming part ofLetters Patent No. 10,467,,daltedJtinuary 31, 1854.

Be it kno'wn that I, ENOS BOGH'ION, of East Bloouitield, in the county of Ontario and State ofNew York, have invented a new and useful'impleinent for the cultivation ofthe soil, for the extermination of thistles and other obnoxious weeds, plants, or grasses growing` therein, which l eall Thistle-1)igger; and I do hereby' declare that the following is a full, clear, and exact description ofthe construction and operation of the saine, reference being, had to the annexed drawings, making a party ot'this specification, in whieh- Figure 1 is a perspective view of the ma` chine, and Fig. 2 is a side view of the lever.

The nature of my invention consists in running; the knife in nearly a iiat position at any required depth under ground, and thereby cutting up and loosening the soil, and also'cnt- 'ting oli' the roots ot' thistles, &c., growing therein, and thereby causing them to wilt and die. v

To enable others skilled in thc artl to make and use my invention,[ will proceed to descriheits construction and operation.

The fratrie A, Fig. 1,is made in any conven-v ient form of timber. The knife may be made of steel or any other suitable material, and should, for the sake of clearing itself from obstructions, be made pointed, as seen at 0, Fig. 1. f

-B BV are the brackets or supports for the knife C, and :should be made of iron, and of any suitable form or size possessing the necessa'rystrengtli. They are boltedonto the bottom of theliame A and securely fastened by bolts, rivets, or otherwise on the under side of the knife, as shown at T T. v y O is the pole, which is made fast toth'e "frame by bolts or otherwise. v The frame, with the knife attachethis raised or lowered by means of the levers K K, operating ripeti the ratchet-wheel H H and turn ing thc-shafts E E, on the outer end of each of which there is a small pinion,"(not seen-,) the the cogsof which operate upon the cogs ou the front edge of the rack N, causing it to slide up and down in the slide' or ruck frame M M. The machine is here represented with the knife drawn up above the top of the ground.

On the outer side ot' the rack or slide N is au axle orarm, upon which run the wheels D D, as seen at P, tofasten the machine in any required position. l

1 I are' two cog-wheels on the shafts E E,l into the cogs ot' which drop the dogs L L,one of which is thrown back to give a clearer view.

lThe construction ot' the levers is shown iny Ris au oblong lioleexteudmg crosswise'of the lever. S S are-two statlouary dogs,

Fi g. 2.

one on eaeh edge ot' the lever. The lever is slipped onto the shaft E E by means of the pole by theside of ther.j|tchet-wheel H H. The dogs S S should be far enough apart so that; when the shaft occupies the center of the hole in the lever neither of them will, touch. the wheel. Then either of the dogs may be thrown into gear by moving the lever on the shalt.

I'do not claim any part of the raising and depressing device, nor do I claiin the knife or the wheel separately; but 1 What Ido claim isl The combination of theknife with thc wheels, for' the purpose ot' cutting up the ground and destroying thistles or any other .obnoxio sf "f weeds, plants', or grasses'growing therein.
